Erosion of Earth's topography entrains sediment in rivers flowing across mountains, canyons and other naturally steep landscapes within the catchment. This silt, sand and gravel is transported variably by suspension in the ...
Researchers using NASA's James Webb Space Telescope have detected evidence for quartz nanocrystals in the high-altitude clouds of WASP-17 b, a hot Jupiter exoplanet 1,300 light-years from Earth.
